Renting a dedicated server sounds like a solid plan for your needs. You're spot on - with a dedicated server, you essentially lease an entire physical machine, giving you exclusive access to its resources. While some basic knowledge of command-line interfaces can be handy, many providers offer user-friendly interfaces and support guides. I've had good experiences with eWebGuru for dedicated servers; they offer affordable options and helpful support. Check out their offerings at https://www.ewebguru.com/dedicated-server-hosting.html. Anyway, good luck with your setup.
